So, what's your favorite free play 9-ball game?

I was just doing a search for 9-ball pool games on the big G (the only search engine that people use) and found a particularly crappy online 9-ball game from TeaGames.com here.

It looks like it was developed a hundred years ago and is not good if that's all you thought was available online for free play 9-ball games.
